The Burns Family Children's Hideout is the Burns Family Children's secret treehouse.
All sets of quadecaplets have six parts of it to themselves because it contains six rooms.
The fifth set of quadecaplets Daniel, Finn, Darragh, Donal, Eoghan, Lorcan, Harry, David, Dwayne, Blaine, Alexander, Darryl, Robbie and Pat Burns' room is painted blue.
The sixth set of quadecaplets Edel, Amanda, Victoria, Darrien, Aoife, Clodagh, Shona, Stephen, Tyrone, Grant, Nathan, Jack, Francis and Ethan Burns' room is painted purple.
- The treehouse was used to hide the kids from their parents Nicola and Lewis when they refuse to do something they don't like
